2. In the lastweek we heard that viable sperm was grown in-vitro; A team of scientists in China say that they successfully grew mouse sperm from embryonic stem cells and that the resulting sperm cells have been used to successfully fertilise an egg, producing healthy, fertile young.

4. 3D printing took another step forward with this bioengineering transplant.A team of bioengineers in North Carolina revealed that they successfully printed an organic human ear and then transplanted it onto the back of a mouse, where it not only survived, but grew.

5. And finally… not exactly international news, but a nice little first for Science Wows; you may have noticed that I published a mini science magazine here (and here for a mobile version) all about the science of pancakes! I have had the idea for a children’s science magazine for a very, very long time; this mini magazine was my first realisation of that idea; With a lot of determination, hard work and luck, a full blown magazine may become a reality. So, if you checked it out, I’d really, really love your feedback; Please let me know in the comments below, or get in contact in other ways.

These are only some of the science events from February, have you any more to add?
